ANDREW P. OLSON, OF CHICAGO, ILLINOIS.

RADIATOR.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed-May 20, 1913. Serial No. 768,745.

To all whom it may concern Be it known that I, ANDREW P. OLsoN, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Radiators, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to radiators for explosive or gas engines andconsists in the matters hereinafter described and then pointed out inthe appended claims.

In the accompanying drawings illustrating a practical embod ment of myinventionFigure 1 is a side view of an explosive engine equipped with myinvention; Fig. 2 is a front view in elevation of the parts of Fig. 1;Fig. 3 is a rear view in elevation of the radiator casing with the fanand water distributer omitted; Fig. 4 is a vertical sectional view onthe" line 44 of Fig. 3; Fig. 5 is a side view in elevation of the fanand water distributer; Fig. 6 is a front wiew of the same, and Fig. 7 isa detail view.

In the drawings the reference numeral 10 indicates the cylinder of a gasor explosive engine of any type in which water-cooling is employed, itbeing understood that as many cylinders may be used as may be required,provided with water circulating outlet pipe 11 and inlet pipe 12 bywhich water is usually supplied to the water-j acket by a pump 13 in thesupply pipe 14, the pipes 11 and 14 communicating respectively with thetop and bottom of the radiator. The casing of the radiator is of sheetmetal of any suitable size and shape having front, 15, rear, 15, sides,15", to 15, and bottom, 15, walls. The casing orms a water-collectihgchamber and its lower portion provides a water reservoir or tank. Thepipe 11 leads through the upper portion of the.

rear wall to an upper header 16 located in a. recess 17 formed by aninset 18 in the upper portion of the front wall of the radiator as shownin Figs. 2 and 4 and provided with a plurality of dependingwater-cooling or radiating tubes or ipes 19 uniting in a lower header 20at t eir lower ends, the lower header being located at about'the centerof a circular passage 21 formed in the front wall of the radiator. Atthe opening 21 and co-incident with its periphery a rearwardly extendingcylindrical wall or partit1on 22 is secured which is slightly flared orenlarged toward its rearedge which extends within but circumferentiallyclears a corresponding circular passage 23 in the rear wall of theradiator as shown in Figs. 3 and 4 to leave an annular opening 24between theperiphery of the passage and the partition. The cylindricalpartition forms an intermediate drum which is of less diameter than theheight and width of the body of the radiator so that passage is aflordedbetween the two, and the lower portion of the drum is provided with adoor 25 hinged at 26 and having a suitable latch 27 to allow water to bepoured into the lower interior portion of the radiator casing whichforms the tank or reservoir with which the watersupply pipe 14communicates. The space between the inner sides of the radiator casingand the drum 22 is provided with retarding or bafiie plates which may bearranged in any suitable manner, and in the practical form shown Iprovide upper and lower imperforate plates 28 and 29 respectivelyextendin outwardly from the drum toward the si es of the radiator bodywhere they afford lateral passages 30 and 31 respectively, and also withupper and lower perforated lates 32 and 33 respectively which preferablyare slightly dished at their centers, the plates 32 being intermediatethe plates 28 and 29. Below the drum and extending across the depth ofthe radiator casing I place a pair of oppositely inclined bafile lates34 and 35 which extend from poslte' sides of the radiator body anda 0rdopposite lateral passages 36 and 37 respectively, the latter leadinginto the water tank or reservoir formed by the lower portion of thecasing. Where the radiator is associated with external engine crankingdevices, such for example as the handle shown at 38, the lower ortion ofthe tank or reservoir is provided with a passage for the extendedportion of the engine crank-shaft 39 formed by an arched partition orwall 40 which then dlvides the tank into opposite chambers which areconnected. by a pipe 41 so that the water supply pipe '14 may draw fromboth. The pipe 41 is detachable so that the radiator can be assembled onthe machine.

The fan 42 is provided with ,a shaft 43 supported in a suitable bearing44 and driven in any suitable manner as for example'by a drive pulley 45which is driven by a belt 46 from a pulley 47 on the engine shaft 39,the shaft being located co-axiall with the drum. The fan is provided wita hollow hub 48 closed at the rear and having an axial circular opening49 at its front to receive the free end of a pipe 50 secured to thelower header 20, the arrangement being such that the pipe and hub makea'suitable joint to allow the latter to freely revolve about the former.vided with a plurality of radial discharge pipes 51 preferably arrangedtangentially on the hub and at a short distance from the fan blades sothat air circulates between them, and each having a water-deflectorplate 52 located in the hub at the opening to the pipe; as shown in Fig.6 when the hub revolves in the direction of the feathered arrow thecentrifugal action will cause the water to enter the pipes as shown bythe featherless arrows. The pipes 51 extend radially to substantiallythe outer line of the fan blades where they connect with the interior ofa peripheral annulus or circular rim formed by the ipe 53 which isdivided into chambers, pre erably one for each radial pipe, bypartitions 54 preferably placed intermediate the openings of adjacentpipes. Each chamber of the annular pipe 53 is provided slightly in therear of its partition considered with reference to the direction ofmovement of the pipe with an air vent or supply opening 55, and adjacentits partition or closure 54 with a dis'chargeor exhaust opening 56having a discharge pipe 57 which is curved. and extends through'theannular passage 24 into the interior of the radiator body and outsidethe drum. Each air vent 55 is provided with an air-intake or deflectorplate preferably in the form of a forwardly directed outwardly flaredfunnel 58"hy which the air is directed under pressureint'o thecorrespondin chamber of the annular pipe 53 when the an revolves.

When the fan and water-circulating pump are operated water is drawn bythe latter from the supply in the tank or reservoir in the lower portionof the bod of the radiatorand is circulated through t e water-jackets ofthe engine cylinders to the return pipe 11, header 16, cooling orradiating pipes 19, and lower header 20 from whence it to the hub 48 ofthe fan'and by centrifugal action through the pipes 5 1 to the chambersin the annular pipe 53 and out throu h the 'exhaust pipes 57 by which itis. (115- charged into the interior of the body of the radiator beyondor outside the drum. As the pipe 53 revolves with .the fan-in the ditionof the feathered arrow in Fig. 5, atmospheric air is forced by thefunnels 58 The hub is pro- EASSGS.

into the chambers of the pipe in advance of the water content of eachchamber and is mixed with the water therein and dis-' charged with thewater through the exhaust pipes 57 in a finely divided aerated sprayaround the drum 22, the air serving to cool the water. The particles ofwater pass over one or more of the bafile plates according to theirrespective points of exit from the pipes 57 and are further cooled inthe passage back to the tank, the surplus air passing out of theinterior of the body of the radiator through the annular opening 24. Bythe time the water reaches the tank its temperature is reduced to apoint sufiicient to enable it to again act as a cooling medium for theengine cylinders.

While I prefer to employ radiating pipes, such for example as shown at19, in front of the fan to initially reduce the temperature of the watercoming from the waterjackets of the cylinders, I may dispense with gheinand lead the water directly into-the It frequently occurs. in coldweather that the circulation of the water by the construction describedcools it below'a desirable temperature, and I may therefore arrange acut-ofl whereby some or all of the water coming from the pipe 11 may becut off from the revolving distributer and returned directly to thetank. For this purpose I may provide a bypass controlled by a suitablevalve; this may be suitably accomplished by providing thelower headerwith an outlet pipe 59 leading to the tank or reservoir and a valve 60which may be turned by its handle 61 to position to alternately open andclose the pipes 50 and 59, either wholly or partially according to therequirements of any conditions of use. Where such by-pass is employed Ipreferably employ a pair' of pipes 59 whose communication with theheader is controlled by the valve and whose lower ends are spread apartso as to brace and steady the header- Various changes may bemade withoutdeparting from the scope of my invention; for example, the revolvingdistributer may be used with or without a circulating pump as thecentrifugal action of the distributer may besufiicient to draw the waterfrom the tank, and with. or without the radiating 1 collecting chamberof the casing.
